Probably not Domain Invasion rotation speed, but at least a few times a day I would expect to see a Level 15 Besieged rolling through.
That's certainly better and I won't complain, but if you ask me it's still nowhere close to where it should, personally.
My problem with this is that unless you have a somewhat regular schedule (once every hour? once every two hours? Something like that) it becomes impossible.
You login and you're doing something else, even in the chance you manage to get the message that Besieged is about to happen (does that KI even work reliably for that?) what are you supposed to do, drop everything you're doing and go do besieged?
It would've been fine 10 years or more ago but the world has changed, MMOs have changed, our lives have changed, do you really expect to plan my in-time game around the remote chance that besieged MIGHT happen?
That's incredibly unefficient and frustrating.
I don't demand being able to do Besieged whenever I want, but I need to at least have a somewhat predictable schedule. Knowing that it's gonna happen exactly 16 hours from now, that would be a good enough compromise, even if the window is large at least I know it's gonna happen.
